MEANS FonRnUTILIzING STEAM. .i

Application mea June is, 191e. seriai Nol 304,454.

the same inventor for patent for locomotive,`

1,292,399, dated January 21, 1919, and relates more particularly to means governing the admission of steam into the turbine from the ordinary driving Vmechanism of the locomotive or of shutting off the same.

For a complete understanding of the invention reference is to be had to the following description and the accompanying drawings in which:

Fig. 1 is a side elevation of a locomotive of the type shown in my prior Patent No. 1,292,399, the turbines and some of the connections thereto being shown by dotted lines Fig. 2 is a section through the smoke box of the locomotive and shows the passages for the steam to the driving engines of the locomotive and for the exhaust steam therefrom to the turbine that operates the suction fan.

Fig. 3 is a longitudinal sectional view of the turbine and suction fan driven thereby, and

Fig. 4 is a diagrammatic View of the locomotive engines andthe turbine that drives the suction fan and the steam passages therebetween.

Referring to the drawings, it will be seen that the steam generated in the boiler 1 is supplied through the divider 2 (see Fig. 2) to the locomotive driving engines 5 by way of pipes or passages 3` and 4; to the steam chests 5*". The steam exhausts from the engines 5 into the passages 8 and 9 controlled by valves 16 and 17, shownmore clearly by (Fig. 2, and from these passages the exhaust steam passes by way of the pipes 10 into the turbine 11, shown in detail by Fig. 3. "The connections between the engines 5, valve controlled passages 8 and 9, and turbine 11 are shown diagrammatically by Fig. 4. `Valves 16 and 17 are mounted on valve rods 2O and are operated by reach rods, not shown, from the cab, throigh levers 19, as will be readily understoo Y As describedkby my patent above referred i to,.No. 1,292,399, the turbine 11-.isY actuated by the steamthat impinges onthe cone 13 being thereby driven together with theshaft 14 to which is fixed at one end the pinion 24 and at the opposite end the fan 23. Y The turbine thus acts as an auxiliary driving means for the locomotive and also actuates the fan 23 to create a suctio-n in the smoke box of the locomotive and, through the fire tubes that communicate betwe'enthe smo-ke box and the fire box in the usual way, the suction is communicated to the fire box and in this way fuel is ldrawn into the fire box and smoke, cinders and other products of combustion are drawn from the fire boxl vthrough the pipes 25 into the turbine 11 tion. It will be seen that means is provided for supplying exhaust steam from the I locomotive engines 5 on each side of the locomotive to the turbine 11 by way of passages 8 and 9 which are connected to the pipes 10 that lead to the turbine 11.

The passages 8 and; 9 are controlled by valves 16 and 17 ,as previously described and in this way the turbine 11 can be put into and out of operation.

Having thus described* my invention,

what I claim is 1. In combination with the driving en- Y gines of a locomotive, a turbine and means for supplying exhaust steam vfrom the driving engine on each side of the locomotive to said turbine, said means comprising a plurality of passages,eachpassage constituting connection between a locomotive engine and the turbine.

2. In combination'V with the driving engines of a locomotive, a turbine for auxiliary power purposes, a valve casing having y neotions from the engineson each side of 10 the locomotive with said Valve casing, and connections from the valve casing to the turbine, whereby steam from the locomotive enp'ines may be supplied to the turbine.

n testimony whereof L hereunto ailix my 15 sign avt-ure.

FREDERICK L. MCGAHAN.
